Research Of Test Scenario Generation Based On UML Model And Implementation Of Supporting Tool

With software development from traditional structured method to object-oriented method, and model driven architecture method put forward newly, it has a very great impact on software test and brings the new challenge to the research and practice of software test The heterogeneity software system represented by the component system, the distributed software, and the embedded software is becoming the main trend of present software development Many modes characteristic of the heterogeneity software at hardware and software platform cause a great deal of particularity in development and test of this software so that the software test is facing a new problem. Currently it is in urgent need to find a solution to testing technique fitting for the heterogeneity software.In recent years, UML is widely as a standard used in the systematic modeling of the software in academic and industrial circles. In the test perspective, these models are the source of obtaining systematic structure and behavior message, therefore they are the ideal test-engendering foundation, which inherently gives rise to the model driven test which is conductive to making the test job begin as soon as possible, removing the defects introduced in the course of software development. No previous standard and method are accepted universally, and test automation depends on the specification or accuracy of design in the test process.The article has considered the application scope of UML sequence diagram, UML collaboration diagram and UML activity diagram of UML dynamic model, and analyzed test model of the corresponding test level. The conclusions are as follows: firstly, UML sequence diagram can be applied as the test models for system test and integration test. Secondly, UML activity diagram model is capable of describing...
